3923164 392-3164 Engine Piston for Dongfeng Cummins 6ct8.3 Piston Assembly

Specification

The 3923164 (392-3164) piston assembly is compatible with 8.3L 6-cylinder engines, serving as a core moving component. It includes the piston body, piston pin, and circlips, made of high-corrosion-resistant materials (e.g., high-nickel cast iron/reinforced aluminum alloy). The piston head features a combustion chamber structure tailored to this engine model, with precision-machined surfaces to match cylinder liner dimensions. It is suitable for assembly and maintenance of power systems in heavy-duty construction machinery, commercial vehicles, etc.

Product Advantages

1. High Durability:Made of wear-resistant and high-temperature-resistant materials, combined with cylinder liner plateau honing technology, it significantly reduces oil consumption and extends component service life;
2. Strong Compatibility:Precision-machined to original specifications, it perfectly matches the cylinder block, piston rings and other components of 8.3L 6-cylinder engines, enabling easy installation;
3. Low Failure Rate:Integrated structural design reduces fit errors between components, adapts to high fuel injection pressure conditions, and lowers the risk of power system failures;
4. Environmental Adaptability:Withstands complex working conditions such as heavy loads, high/low temperatures, and meets multi-scenario power demands.

Product Performance

1. Power Matching:The combustion chamber design tailored to this engine model, combined with a high fuel injection pressure system, ensures full fuel combustion and supports the engine’s rated power and torque output;
2. Wear Resistance:The combination of piston surface technology and corrosion-resistant materials can withstand friction from long-term high-frequency reciprocating motion, reducing abnormal cylinder wear;
3. Sealing Performance:Works with piston rings to effectively seal the combustion chamber, preventing gas leakage and oil intrusion into the combustion chamber, and maintaining efficient engine operation;
4. Temperature Adaptability:Excellent thermal stability of materials allows it to maintain structural stability under high-temperature engine conditions, avoiding deformation and failure.
